adequately fastened.
CAUTION: Over-tightening the terminal nuts can cause damage to the terminal, under-tightening can
cause a loose connection and excessive heat during operation, make sure to use the prescribed torque.
3. Install the fuse holder or breaker in the positive battery cable (or negative, if the battery must be positive-
grounded).
WARNING: Ensure the fuse is not yet installed or make sure the circuit breaker is secured in the open
position for the rest of the installation procedure until instructed to do otherwise.
4. Connect the other end of the battery cables to the battery. Ensure the polarity of the battery terminals on the
Any-Grid match the battery polarity.
CAUTION: Reverse polarity connection to the battery may damage the unit.

AC Input and AC Output Connection
WARNING: Before connecting an AC source to the AC input of the Any-Grid, install an AC circuit breaker
between the Any-Grid and AC input power source. This will ensure the inverter can be securely disconnected
during maintenance and fully protected from over current of AC input. Make sure the breaker is open / off for
the rest of the installation procedure until instructed otherwise.
WARNING: Ensure that the installation has adequate grounding and connect the protective earth (PE)
terminals to this ground as instructed below. Failure to do so can cause serious injury or death once the unit is
powered up or the AC source is activated via its breaker.
WARNING: Ensure the AC cables are sized according to the table below. Inadequate AC cables can cause
excessive heat or fire during operation.
CAUTION: Do not connect an AC source to the “AC OUTPUT” labelled terminal of the unit as this will destroy
the unit. Only connect it to the “AC INPUT” labeled terminal.
CAUTION: Only AC sources with a neutral may be used. Using two phases on a single Any-Grid instead, will
cause damage.
CAUTION: Short-circuiting the L (live phase) AC input or AC output terminal to the metal body of the unit will
cause permanent damage not covered under warranty.

Steps to connect the AC source and AC loads:
1. WARNING: Ensure the battery cable fuse is removed or breaker is secured in the open position.
WARNING: Ensure the AC source breaker is secured in the open position and there is no voltage on the
conductors before continuing.
2. Remove 10 mm / 0.4 in of insulation for the six AC conductors (neutral “N”, live “L” and protective earth “PE”
for the AC source and loads).
